WebM to text

WebM to text

Upload a WebM file and get the speech in it as text. WebM is what browsers and many web tools record: in-browser screen capture, meeting-room widgets and downloaded web video. Both video and audio-only WebM are accepted.

What WebM is

WebM is a web-oriented container based on Matroska. Video is typically VP8 or VP9 and audio is Vorbis or Opus. Browsers' MediaRecorder API writes WebM, so recordings made inside a web page almost always end up as .webm. Audio-only WebM exists too, and some recording tools save voice notes that way.

Where WebM files come from

  • Screen and tab recorders that run in Chrome or Edge.
  • Web-based interview or survey tools that record answers in the browser.
  • Downloaded web video that was served as WebM.
  • The recorder on this site's own record page saves what you capture for transcription directly.

Steps

  1. Locate the .webm file (browser downloads folder for most recorders).
  2. Choose it above; no conversion needed.
  3. Correct and export. If you need subtitles, see WebM to SRT.

Quirks

  • Browser-recorded WebM often has no proper duration header, so a player's seek bar looks wrong. The audio still decodes normally.
  • If a recording was made without microphone permission there is no speech to read.
  • Tab recordings capture the tab's sound, not your microphone, unless you chose both.

How it works

  1. Add a recording

    Drop in a video or audio file, choose one from your device, or record from the microphone. Nothing to install.

  2. It transcribes

    Speech becomes timestamped text, with speaker labels when more than one person talks.

  3. Read, fix, export

    Click any line to correct it, then download TXT, subtitles, Markdown, JSON or CSV.

Questions

Why does my WebM show no length?
Browser recorders stream the file and sometimes skip the duration field. It does not stop the audio being transcribed.
Is there a faster way than uploading a WebM?
If you are recording right now, the record page transcribes straight from your microphone.
Can I transcribe audio-only WebM?
Yes.
Is it free?
Yes — one file up to 15 minutes and 25 MB with no account, up to 3 tries a day. A free account keeps your transcripts in a library and lifts the guest limits; the current limits and paid plans are on the pricing page.
What can I export?
Plain text, timestamped text, SRT, VTT, Markdown, JSON with word timings and CSV, all from the same edited transcript.
